\multicolumn{7}{p{16cm}}{\textit{Notes:} OLS regressions comparing fully grandfathered boilers (GF$^{F}$) with partially grandfathered boilers. The sample used and non-environmental controls (i.e., boiler-level and market-level controls as well as year, state, utility type and manufacturer fixed effects) as in specification (3) in Table (1). Boiler-level clustered standard errors used, with *** p$<$0.01,  ** p$<$0.05,  * p$<$0.10 and \textit{t}-statistics in parentheses.} \\
